Abstract

Polysaccharide S-119 is used as a desensitizer in lithographic fountain solutions to maintain non-image areas on a lithographic printing plate in a hydrophilic condition in order to prevent scumming or ink pickup in said areas. S-119 is prepared in aqueous solution which is added to phosphoric acid etch in water plus alcohol to provide a gum concentration of 20-1000 ppm by weight in the fountain solution.
